Kris Jenner's boyfriend Corey Gamble was spotted splashing the cash in designer stores in Beverly Hills, after it was claimed she pays him $20,000 a MONTH to help take care of her and her kids.

The momager, 60, has been dating the 35-year-old music executive since last summer, following her split from ex Caitlyn, and their relationship is reportedly on the rocks because he is demanding more money, according to US OK! Magazine.

But Corey didn't seem too bothered about the shocking claims as he was spotted out shopping carrying a large black Chanel bag after a rather pricey purchase.

He was dressed in a grey tshirt with black jeans and boots as she strolled past snappers with the bag, which could have been something he was picking up for Kris, or maybe not if the latest report is to be believed.

A source said: "He has been babysitting Kris' kids and even runs errands for her and acts as her official masseur. He figures what he is being paid is nowhere near enough."

Their relationship is said to be "crumbling" and he is reportedly making more and more demands from Kris.

It is also not known exactly what role Corey plays in boosting Bieber's career, or what he's paid by the pop star, who is about to kick off his Purpose tour to promote his award-winning new album.

Kris and Corey looked happy during a family movie night recently, watching The Brothers Grimsby with controversial star Sacha Baron Cohen and his wife Isla Fisher, as they laughed out loud at shocking scenes.

They were also pictured at Paris Fashion Week and cuddling up together at Kanye West's Yeezy 3 show in New York City last month.

We're surprised Kris hasn't jumped to his defence and joined Kanye and Kim by going on a Twitter rant.
